Hannaford Supermarkets is alerting customers to a recall of nearly 30,000 pounds of ground beef, potentially contaminated with salmonella.

Cargill Beef is recalling the product, the Boston Herald reports, a batch of 85 percent lean ground beef, produced May 25 at Cargill's plant in Wyalusing, Pa. Kansas-based Cargill Beef is part of privately held Cargill Inc.

"Food borne illnesses are unfortunate and we are sorry for anyone who became sick from eating ground beef we may have produced," Cargill Beef President John Keating said in a statement. "Ensuring our beef products are safe is our highest priority and an investigation is underway to determine the source of Salmonella in the animals we purchased for harvest and any actions necessary to prevent this from recurring."
